No, I don't have all the answers but here is what I believe based on my studies ...
.:: FIRST HARVEST ::.
This one has already occurred, these were resurrected after Jesus' resurrection - on the third day after His death/burial. Jesus is the first of the firstfruits and "the many" are the wave offering.
"Jesus, when he had cried again with a loud voice, yielded up the ghost. And, behold, the veil of the temple was rent in twain from the top to the bottom; and the earth did quake, and the rocks rent; And the graves were opened; and many bodies of the saints which slept arose, And came out of the graves after his resurrection, and went into the holy city, and appeared unto many. Now when the centurion, and they that were with him, watching Jesus, saw the earthquake, and those things that were done, they feared greatly, saying, Truly this was the Son of God." {Matthew 27:50-54 KJV}
.:: SECOND HARVEST ::.
This is the resurrection of the dead in Christ followed by the change to immortality of the living in Christ and the rapture of the church! These are the "winnowed" barley harvest. This happens just before the "wrath of the Lamb" (the 7 trumpet judgments).
"After this I beheld, and, lo, a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands; And cried with a loud voice, saying, Salvation to our God which sitteth upon the throne, and unto the Lamb. And all the angels stood round about the throne, and [about] the elders and the four beasts, and fell before the throne on their faces, and worshipped God, Saying, Amen: Blessing, and glory, and wisdom, and thanksgiving, and honour, and power, and might, [be] unto our God for ever and ever. Amen. And one of the elders answered, saying unto me, What are these which are arrayed in white robes? and whence came they? And I said unto him, Sir, thou knowest. And he said to me, These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb. Therefore are they before the throne of God, and serve him day and night in his temple: and he that sitteth on the throne shall dwell among them. They shall hunger no more, neither thirst any more; neither shall the sun light on them, nor any heat. For the Lamb which is in the midst of the throne shall feed them, and shall lead them unto living fountains of waters: and God shall wipe away all tears from their eyes." {Revelation 7:9-17 KJV}
There is NO SIGN of a resurrection nor rapture in Revelation 4 ... NONE. We are at the fifth seal NOW, the martyrs have been ongoing since Jesus' death/resurrection, as has earthquakes, famines, pestilences, wars & rumors of wars, et al {Matthew 24, Mark 13, Luke 17 & Luke 21}.
.:: THIRD HARVEST ::.
WOW - ?how did I miss this? - chapter breaks, that's how! I've known of Rev 14:14-16 being the "tribulation saints" for a couple of years now, but, until today, I didn't realize that carried into Rev 15! This happens just before the "wrath of God" (the 7 bowl/vial judgments). This is the "wheat harvest" (tribulation saints), they have endured the "tribulum" (first half of the tribulation period) and are taken up to Him before the "grapes of wrath" begins (last half of the tribulation period - great tribulation - Jacob's trouble).
"And I looked, and behold a white cloud, and upon the cloud [one] sat like unto the Son of man, having on his head a golden crown, and in his hand a sharp sickle. And another angel came out of the temple, crying with a loud voice to him that sat on the cloud, Thrust in thy sickle, and reap: for the time is come for thee to reap; for the harvest of the earth is ripe. And he that sat on the cloud thrust in his sickle on the earth; and the earth was reaped." {Revelation 14:14-16 KJV}
***CONTINUED***
"And I saw another sign in heaven, great and marvellous, seven angels having the seven last plagues; for in them is filled up the wrath of God. And I saw as it were a sea of glass mingled with fire: and them that had gotten the victory over the beast, and over his image, and over his mark, [and] over the number of his name, stand on the sea of glass, having the harps of God. And they sing the song of Moses the servant of God, and the song of the Lamb, saying, Great and marvellous [are] thy works, Lord God Almighty; just and true [are] thy ways, thou King of saints. Who shall not fear thee, O Lord, and glorify thy name? for [thou] only [art] holy: for all nations shall come and worship before thee; for thy judgments are made manifest. And after that I looked, and, behold, the temple of the tabernacle of the testimony in heaven was opened: And the seven angels came out of the temple, having the seven plagues, clothed in pure and white linen, and having their breasts girded with golden girdles. And one of the four beasts gave unto the seven angels seven golden vials full of the wrath of God, who liveth for ever and ever. And the temple was filled with smoke from the glory of God, and from his power; and no man was able to enter into the temple, till the seven plagues of the seven angels were fulfilled." {Revelation 15:1-8 KJV}
.:: AFTER THE "GRAPES OF WRATH" ::.
There are no other harvests that I can find in the bible aside from the three as shown above. At the end of the tribulation, which most Christians believe is a seven year period, Jesus will return to rule and reign in Jerusalem for 1,000 years, and His resurrected immortal followers will help Him to rule worldwide. Those that make it through the tribulation, alive, will be the ones to repopulate the earth.
Maranatha to our Bridegroom King, Jesus/YeshuaH!
